Calibration - analog outputs

7.4.1

Purpose

Although the transmitter analog outputs are calibrated at the factory, they can be
trimmed in the field to match the reading from a standard milliameter. Both the low (0 or
4 mA) and high (20 mA) outputs can be trimmed.
7.4.2

Procedure

Complete the following steps to calibrate the transmitter's analog outputs.

Connect a calibrated milliameter across the output you wish to calibrate. If a load is
already connected to the output, disconnect the load.
Do not put the milliameter in parallel with the load.
Press MENU.
The main Menu screen appears. The cursor is on Calibrate.
Press ENTER.
Choose the output you wish to calibrate.
The transmitter simulates the low output current.
Change the value in the display to match the reading from the milliameter.
The transmitter simulates the 20 mA output current.
